NoN-sKIDnING TIRE APPLIANCE.

Specification of Letters Patent.

Patented Sept. 8, 1914..

Application filed July 21, 1913. Serial-No. 780,322.

'A The objecitjit' the invention is to provide a "non-skidding devicefor truck vehicles,

,y especially appliqible to automobile tires of "various character. andto furn1sh a nonskidder of such novel and peculiar construction andarrangement of parts as to be expeditiously applied. and which shall not1niure or interfere with the ordinary tlre, but which shall assisttraction and prevent the wheels from slipping orv skidding.

A further object of the invention is to provide. a non-skidding deviceot such novel and peculiar construction and arrangement of parts as tobe capable of adjustment in the application thereof without detachingorseparating the partsl thereof, and to furnish special mea-ns thereinwhereby the skidder may follow every movement. of a cushion or resilienttire.

Various other objects, advantages, and improved results are attainablein the prac tical application of the invent-ion.

In the accompanying drawings forming part ot' this application: Figure 1is a side elevation of a wheel, showing the application of theinvention. Fig. is an enlarged sectional view taken on the planeindicated by the dotted line (n-a. Fig. 1. Fig. 3 is an ele vvation ofthe non-skiddcr loolving` at the periphery. Fig. el is a sectional viewof the clampingI bars and band ends. Fig. 5 is a perspective view of theclamping bars. Fig, (t is a ywrspective view ot one pair of theconnected tread bars. Fig. T is an enlarged sectional view ol one pairol` 'the rigid bars.

The saine reference characters denote the saine. parts throughout theseveral views ot' the drawings.

For the purpose of illustration the device is shown as applied to anaulolnobil@truck wheel l, ha ving a double' rubber tire rlhe manner ot'applying thc device to said tire, or any other ot the well knownresilient tires, will be hereinafter explained.

In carrying out my invention l employ pair of steel spring bands 3,spaced apart so as to engage the periphery of the tire at equal distancefrom the peripheral center thereof. The bands are connected erosswise bya plurality of tread bars et secured to and across the bands bycountersunk rivets 5, and having ends 6 dependingfrom the bandsradiallytoward the axis of the wheel, and said ends project beyond the wheetrim7, and Wheel telly 8 so as to protect said wheel parts without engagingthe same. The said ends 6 are provided with slots 9, and are looselyconnected in tWo sets by means Aof links 10 hung in said slots.. The twosets-.0f bars 1 .are separated by two pairs of tread bars 11, theduplicate of the bars t, and have the saine position relative to thebands 3, as the bars d. Thile the bars 4 of each set are looselyconnected together, the bars 11 are connected together in pairs by meansof a U-shaped rod 12 having screw ends extending through the ends of thebars 11, for nuts 13. The ends of the bands 3 are connected so as toopen and close the skidder in applying it to a tire, and said connectionis` such as to afford means for varying the size of the-skidderaccording to the size of the tire to which it is applied, and in orderto accomplish the same I employ a pair of cross-bars 14 similar to thebars l and 11, except that the bars 14 have enlarged ends 14a for bolts15, provided with suitable nuts" 1G. One end of each band is secured toone of the bars 14, and the other of the bars 14; is secured to thebands so as to leave the other end of the bands projecting for thepurpose oi having the bandsover-lap and for afford! ing a length ofbands sulicient to permit the skidder to be applied to tires of varioussize without leaving a space between the ends of the bands. The ends ofthe bars 14 are .linked with the adjacent bars Ll, and the bolts 15 areof sufficient length to permit variation in the size ot' the skidder.The bars 14 form a tread clamp for the bands. It is obvious that theskidder may be applied to and removed 'from a tire by removing the bolts15, so as to permit the skidder to be opened suliciently to be slippedon or cti the tire, and without detac-hing or separating any other partor parts of the ski dder.

It has been found that in connecting all the tread bars together byconnected links xed to each bar such means of connection will not permitthe device to be opened sufico'- ticien tly t'or applying and removingthe same,

therefore certain of the bars are connected in pairs by the U-sliapedrods which are removed in applying and removing the device so as topermit tlie device to be spread fully open for at least halt itscircumference. It will be seen that the rod-connected bars are separatedby removing` the rods 12, that the clamping ends of the bands 3 may besprung open to any extent desired, and that the pairs of bolted bars llseparate the bars et into two sets, one of such sets adapted to begiven. Wider opening movement than the other set.

I do not Wish to coniine my invention to V any particular size, shape,or material of which it is or may be made, nor to limit the same in itspractical manufacture and application, but reserve to myself the rightto make sucli changes and variations therein as may come Within thescope of the appended claims.

I-Iaving thus described my invention what I claim as new and desiretovsecure by Let` ters Patent is l. A non-skidding tire appliancecomprising a pair of resilient bands for encircling the tire, clampingtread bars connecting the bands, a plurality of tread bars secured toand extending across the bands and having ends projecting over the sidesof the tire, removable rods connecting certain of the. plurality of'tread bars, and means for ieXibly connecting the rod-connected bars withthe other tread bars.

2. A non-skidding tire appliance comprising a pair of resilient bandsencircling the tire, a plurality of tread bars secured to and extendingacross the bands and having projecting ends, clamping tread barsconnecting the bands, two pairs of tread bars secured to the bands andconnected in pairs for separating said pluralityof bars into two sets,rods connecting said pairs of bars and adapted to be removed so as topermit one of said sets to be swung open, means for loosely connectingone set of the bars With a bar of each of said pairs, and means forloosely connecting the other set of bars With the other bar ojf saidpairs and with the clamping bars.

3. A non-skidding tire appliance comprising a pair, of resilient bandsencircling the tire, a plurality of tread bars secured to and extendingacross the bands and forming a continuous tread and having radiallydepending ends, rods connecting certain of the bars in pairs and adaptedto be removed for spreading these bars apart, a tread clamping membersecured to each end of the bands and` having slotted ends, and means forloosely connecting the said depending ends together and with therod-connected bars and with the clamping members.

In Witness whereof I hereunto set my hand in the presence of twowitnesses.
